most laptop power supplies support full range power input. meaning it will accept any normal outlet voltages used anywhere. if you look at the power supply of your laptop it should say vin (voltage in) 100v to 240v 50/60 hz, or close to that if it is.

This condition can be caused by plugging in an adapter that has polarity reversed (that's what I did with an after-market power supply). Your battery is probably not bad (I changed to a brand-new battery, and it still had the same problem). However, the problem is deeper: I'm tracking down which component on the power board was burned out when this happened. No luck so far.

Sound like you may have the wrong power cord for your unit. The original power adaptor for the A105 is 75W (15V x5A) Auto sensing 100-240V/50-60MHz frequency input. If you got a replacement adaptor, I would reccomend a 75W or higher adaptor. (A new opposed to a used one.) Good Luck.

Your phone did expirence a surge that probably blew the ac adaptor which happens most of the time, u can buy one of those universal adaptors and look on the back of the old adaptor for the output voltage it will usually read between 3 and 8 volts DC.Set the universal adAptor voltage to the setting right below the voltage output on the back of the ac adaptor.

If you can find an adapter with the same Connector, Polarity,Voltage. and the required Amperage or higher, it should work.

You might be able to find the exact part on Ebay or an online store.

Is the power adaptor made for the country you are living in? It's possible the plug you are plugging it into has a higher current than the plug was certified for. Have you tried plugging the laptop in in another location (like, in a different building)? You may just need to replace the adaptor, how old is it?
